photosensitive polymer

Examples of the changes in photosensitive polymers are a change in molecular shape (photo-responsive polymer), a change in its constitution (photo-reactive polymer), and a reversible change in color (photochromic polymer).

Photosensitivity in photosensitive polymers means that the polymers are sensitive
to the irradiated light leading to some change in properties or structure. It is different
from photosensitization.
